Age

In 1960 my age was equal to the digits sum of the year of my birth. What is my age now?

Correct answer:

n =  78

Step-by-step explanation:

$n=2021-1943=78$

The equations have the following integer solutions:

a = 1+9+c+d
1960 - (1900+c*10+d) = a
a<40
d<10

Number of solutions found: 1

a₁=17, c₁=4, d₁=3

Calculated by our Diofant problems and integer equations.
